Cultivation method of thorn plum
Fertilize soil or land
Fertilizer is generally given less, and a small amount of fertilizer can be applied in spring and summer. Generally speaking, 1 diluted fertilizer can be applied within 3~4 weeks of Rosa davurica fruit growth period. Excessive fertilization will cause the branches and leaves to grow too vigorously, while the long leaves will not bloom, and the ornamental value will be destroyed. However, a small amount of fertilizer can be applied at the bud breaking stage, so that not only the leaves will flourish, but also the flowers will flourish.
illuminate
As we all know, general plants need sufficient light to flourish, so does Rosa davurica. It's best to have enough sunshine in one year, especially in flowering period. Because it is raised indoors, we need to move the Rosa davurica fruit to a place where it can be often illuminated. Only when the sun is full and the flowers are brightly colored can the leaves flourish. If it is kept in a dark environment for a long time, it will not grow well, because this plant prefers warm to cold.
decrease
Rosa roxburghii flowers grow at the top of new branches. In order to make Rosa davurica fruit bloom more, it needs to be pruned properly. The season and technology of construction also need attention. Never choose to build in flowering period, but pay attention to the main branches, because the main branches are too long and there will be fewer flowers. Therefore, after the flowering period, the branches that are too long and grow irregularly should be cut short, so as to ensure the number and growth of flowers in the next flowering period. Generally, two new branches will grow under the cut of branches, and they will bloom when they are 5~6 cm long. In a few years, the whole plant will be full of bright little red flowers.
Support bracket
Because the branches are slender and soft, with the growth of the plant, the main branches can't bear the weight and are easy to bend, so at this time, bamboo sticks or iron wires can be tied into brackets with different shapes, and the branches can be tied to them to make a style, which not only ensures the growth of Rosa davurica, but also can shape it and add beauty. If we leave it alone and let it grow naturally, its main branches will grow longer and longer, not only with fewer flowers, but also with unsightly plant shape. It is easy to break down.
Growth habit of thorn plum
Plum blossom is a thorny erect or slightly climbing shrub. Strong sex, like warm and dry climate, suitable growth temperature is 18-25℃. If the indoor temperature can be kept above 15℃ in winter, flowers will bloom all winter. If the temperature is too low, all the leaves will fall off and go to sleep. Adequate sunshine is needed in flowering period, and topdressing, organic liquid fertilizer or compound fertilizer can be used once every half month. Suitable for the growth of loose sandy soil.
Thorn plum likes temperature, light, drought, humidity and cold. Born in loose and well-drained sand. The growing season is in summer and autumn, and it is safe to overwinter at room temperature above 3℃ in winter. If it is above 15℃ and there is enough sunshine, it can still continue to bloom.
Propagation method of thorn plum
Plum blossoms are propagated mainly by cutting. Cuttings can be carried out throughout the growth period, but it is best to carry out them in May-June, with high survival rate. Select the branches that matured last year and cut them into a section of 6- 10 cm, preferably the top branches. White milk flowed from the wound. Wash with warm water and dry before inserting into the sand bed. Keep it slightly dry and take root about 30 days after transplanting.
Cutting propagation of Rosa davurica is very easy and can be carried out throughout the growth period. Choose loose and well-drained humus soil as culture soil, and change pots every spring. More water is needed in summer and autumn, so water it in time. If the temperature is above 15℃ in winter and spring, it can bloom continuously. If it is kept in the shade for a long time, it will not bloom. When the branches are too crowded and dense, they can be pruned and reshaped before new leaves grow in spring.
Rosa davurica is a succulent plant, which is drought-resistant, so watering is not suitable. Because it is sandy soil, it has good water absorption and can keep the soil moist for a long time, which is beneficial to its growth, so it can grow well without long glue. If the plastic basin is too wet, it will not only cause rotten roots, but also endanger the survival of plants. So it's better to do a little dry and water the basin soil at ordinary times. In summer, water evaporates quickly, so the water should be moderate, and in winter, it evaporates slowly, so the water should be moderate.
Basic introduction of thorn plum
Plum blossom, also known as Haitang, originated in Madagascar, Africa. I like a warm, humid and sunny environment. High temperature resistance, not cold resistance. Humus soil with loose drainage is the best. The temperature in winter shall not be lower than 12℃.
At the top of each branch, the thorn plum grows a tender stem near the leaves. At first, two or four blue-yellow buds smaller than mung beans grew on each slender stem, and the buds gradually grew up and became two petals after unfolding. Soon, the two small petals changed from bluish yellow to pink, and the stamen in the middle gradually emerged. The blooming thorn flowers look like rubies and little stars from a distance; At close range, it looks like the smiling face of a little doll and the red lips of a little girl. When all the flowers on the branches are in full bloom, a little red in the green leaves is even more beautiful and lovely. Matters needing attention in plum cultivation
